Strange Happenings: Bubbles on a Hermit Crab in a Shell

It was Fall in Florida and we were boating. When I was walking around a muddy island at low tide I came across this strange sight. A mound of bubbles in the sand.

The snail was not in the pear whelk shell, it was a hermit crab inside. I began to see his legs poking out through the foam. I have tried to research this phenomenon and have had no luck.

This is the first and only time I’ve seen something like this. No other shells / hermit crabs on the island were doing this. If you know, I’d love to hear.
